TV tonight: a special 100th birthday party for David Attenborough

David Attenborough’s 100 Years on Planet Earth 8.30pm, BBC One Happy 100th birthday to David Attenborough! A week of celebratory programming has led up to this special live extravaganza at the Royal Albert Hall in London. The BBC Concert Orchestra will accompany the 90-minute journey through the veteran broadcaster’s most remarkable moments over the last century. Prepare to be left in awe – and probably a wee bit emotional, too. Hollie Richardson Gardeners’ World 7.30pm, BBC Two Can you dig it? This edition of the green-fingered gazette comes from the RHS Malvern spring festival in Worcestershire, with Rachel de Thame and Joe Swift seeking out the show’s horticultural highlights. Elsewhere, there is a flower-pressing masterclass and a pleasingly retro showcase of 1970s houseplant chic. Graeme Virtue Bradley & Barney Walsh: Breaking Dad 7.30pm, ITV1 The father-and-son presenters of Gladiators – the Glad Lads? – continue their latest road trip rolling around Australia. While there is banter aplenty, the overarching theme remains “bonding through adversity” – this week that includes a vertiginous ravine traversal and a demanding sheep-shearing challenge. GV Hacks 9pm, Sky Atlantic The acidic, Emmy-winning showbiz comedy has gone a little syrupy in its final season but, really, it’s still a total hoot. In this double bill, Deborah (Jean Smart) is courted by an AI startup, before she and Ava (Hannah Einbinder) lean into their affectionate side when they’re mistaken for a couple. Hannah J Davies St Denis Medical Escalating farce ... St Denis Medical. Photograph: BBC/NBCUniversal Media, LLC/Justin Lubin 10.40pm, BBC One A nicely constructed piece of escalating farce drives this week’s first episode of the US mockumentary. Nurse Alex tells mischief-making doctor Ron that she and her husband keep no secrets from each other, with embarrassing consequences for everyone. In the second instalment, Joyce feels the nurses aren’t sufficiently appreciative of Nurse Appreciation Week. Jack Seale TFI Friday Unplugged 11.05pm, Channel 4 The peculiar journey of this lo-fi chatshow from 90s cultural juggernaut to YouTube indulgence then back to broadcast TV continues. The late-night slot gives Chris Evans a chance to retain a freewheeling approach as he welcomes another selection of guests and bands. Phil Harrison Film choice Downton Abbey: The Grand Finale (Simon Curtis, 2025), 7.55am , 8pm, Sky Cinema Premiere The last movie ... Laura Carmichael, Harry Hadden-Paton, Elizabeth McGovern, Hugh Bonneville and Michelle Dockery in Downton Abbey: The Grand Finale. Photograph: Rory Mulvey/AP After 52 episodes and two films, if you haven’t fallen for the Upstairs Downstairs goings-on of the landed Crawley family, then this third and last movie is probably not for you. For the rest, the main scandal to get the aristocrats’ sensibilities all a-quiver is the divorce of Lady Mary (Michelle Dockery), which in 1930 prohibits her from being presented to a prince and awarding prizes at the county fair. There’s also some distressing money talk involving Cora’s brother (Paul Giamatti), plus a guest appearance by Noël Coward. Spiffing.
